A new development that will provide 5% of UK gas demand has started exporting to the mainland.
The Cygnus field, located 150 kilometres off the coast of Lincolnshire, sent its first load of gas to the Bacton Terminal in Norfolk.
It is expected to produce around 250 million cubit feet of gas each day and could heat around 1.5 million households.
Installations in the 250-square kilometre field include four platforms, 10 wells and two subsea structures.
During its five-year development, the project is said to have added £1.3 billion to the UK economy and supported nearly 5,000 jobs.
Project partners ENGIE, Centrica and Bayerngas are evaluating further opportunities in the area with the aim of bringing additional volume through the new infrastructure when capacity becomes available.
Ruud Zoon, Managing Director of ENGIE E&P UK, said: “First gas from Cygnus represents a significant boost to the UK’s long term energy security with an estimated production life exceeding 20 years. Furthermore, with over 80% of the contract work secured by British businesses – including fabrication yards in Hartlepool, Methil and Burnt island – it is a showcase for the technical and commercial excellence of the UK oil and gas supply chain.”
The new project comes at a time when many other gas platforms and fields in the UK are starting to be closed down.
